Chemical Structure
Description
4-[5-methyl-2-(propan-2-yl)phenoxy]-3-nitrobenzaldehyde (C17H17NO4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO supplies 4-[5-methyl-2-(propan-2-yl)phenoxy]-3-nitrobenzaldehyde (CAS 571153-23-6), a certified reference material (molecular formula C17H17NO4, MW 299.32 g/mol) for analytical method development and quality control.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
